With over 6,000 locations worldwide, you can visit a Dairy Queen near you for a treat that's ‘So Good, It's RiDQulous.' To celebrate its partnership with Children's Miracle Network Hospitals and its loyal fans, Dairy Queen will once again host Free Cone Day this March 20th, 2018. Participating Dairy Queen and DQ Grill & Chill locations will serve fans a free small vanilla soft-serve cone with the signature curl on top, in exchange for a donation to CMN Hospitals. (At participating DQ locations only. Limit 1 small cone per customer.)
